Have to re-apply Go Launcher theme on reboot

I have a neat premium Honeycomb theme on Go Launchr Ex. But my phone either locks up, or reboots itself at times, and when I see my home screen, my wallpaper is intact but Go Launcher is reverted to default. I keep having to reset the honeycomb theme every time. This is annoying. Is Go Launcher meant to disable themes if the phone crashes? This is the first time I have used a premium theme...
